[PATCH v2] r8169: set coherent DMA mask as well as streaming DMA mask

PCI devices that are 64-bit DMA capable should set the coherent DMA mask as well as the streaming DMA mask. On some architectures, these are managed separately, and so the coherent DMA mask will be left at its default value of 32 if it is not set explicitly. This results in errors such as r81
